ARTHUR. G. FIELDS, OF LITTELL, WASHINGTON.

DIRT-SCRAPER.

Patented July 16, 1907.

Application filed February 20,1906. Serial No- 302,008.

To all whom it may concern:

Be it known that I, ARTHUR O. FIELDS, a citizen of the United States,residing at Littell, in the county of Lewis and State of Washington,have invented eertain new and useful Improvements in Dirt-Scrapers, ofwhich the following is a specification, reference being had therein tothe accompanying drawings, in which Figure 1 is a plan view of a scraperembodying my invention; and Fig. 2 is a side elevation of the same.

The object of this invention is to produce improve ments in theconstruction of dirt-scrapers whereby they may be convenientlycontrolled by an attendant in both their filling and dumping operations.

To these ends the invention consists in the novel construction,adaptation and combination of parts as will be hereinafter described andparticularly pointed out in the appended claims;

In the said drawings, the reference numeral 5 designates the scraperbowl, or pan, provided with a rear wall 6 and sidewalls 7, as ordinary.

. Rigidly connected to the latter, and intermediate their lengths, areoutwardly projecting trunnions 8 in axial alinement with each other.Respectively connected to these trunnions are the front and rear ends ofthe handle-bar 9 and the draft bar 11. Each of these bars are desirablyof a U-shape and the transverse member 11 of the draft bar is at such adistance from the pivotal connections as to allow the pan to be rotatedabout the latter without interference with such member. Devices, such asa lug 11 and a link 12, are provided upon the draft bar for connectingthe draft animals thereto. The said handle bar extends to somedistance'to the rear of the pan and has its transverse portion 9 formedcylindrical to furnish a smooth gripping surface for the attendants handor hands. Intermediate the bar part 9 and the pan are cross bars 13 and14 which are apertured at 15 for the insertion of a latch rod 16 havingat its rear end an eye 16 and its other extremity flattened for thepurpose of registering with any of thevnotches 17 of a rack plate 17fixedly secured to the back wall 6 of the pan.

Interposed between the bar 14 and a fixed pin 19, or its equivalent,upon the latch rod is a spring 20 tending to press the rod intoengagement with any of the notches 17 which may be presented andaccording to the inclination desired to be given the handle-barrelatively to the pan. As in other scrapers, the pan is filled by beingdragged forwardly through an advance movement of the team with a properinclination of the pan to cause the cutting edge 5 to enter the ground;and, similarly, when loaded the handle-bar is lowered to remove thecutting edge out of action and the apparatus is thus dragged to thedumping place. Instead, however, of dumping the load by manual labor,with my invention all that is required is for the attendant to elevatethe handle-bar sufficiently to rc-engage the pan edge 5 with the groundwhen, upon the pan being released from the latch red, by continuedforward movement of the team the pan is tilted about its engaged edgeinto the posit-ion indicated by the broken lines in Fig. 2 and continuedthere-beyond to deposit the load and be in a reversed position. The panthen being upside down is reversed into its normal position by theprogression of the team causing the rear edge 5,which is now in advance,to be engaged with the ground and which serves as the tilting fulcrum.After the pan has been brought back to its original position, the latchis re-engaged therewith when the scraper is again ready to be filled.

Having described my invention, what I claim as new and desire to secureby LettersPatent, is

1. In a scraper, the combination with the handle-bars and the draft-bar,of a pan rotutably connected to both of said bars, and manually operatedlocking means comprising a spring-pressed rod carried between thehandlebars, and a plate provided with a series of ratchet teeth carriedby the back of the pan thereby forming means by which the handle of thescraper is adjustably locked, substantially as set forth.

2. In combination with the handle-bars 01 a dirt scraper, a rod slidablymounted between said handle-bars, a fixed pin passing through said rod,and a coiled spring sursaid fixed pin, the other end of said springbearing against the cross-bar or brace of the handle-bars and a ratchettoothed plate carried by the back of the pan and forming means wherebysaid handle is adjustably locked, substantially as Set forth.

In testimony whereof I allix my signature in presence of two witnesses.
